Quasi-static and dynamic simulation of sheet metal forming processes usiing linear and quadratic solid-shell elements

Abstract

A family of prismatic and hexahedral assumed-strain based solid–shell elements (SHB elements), with their linear and quadratic versions, are presented in this work to model thin structures. These SHB elements are based on a three-dimensional formulation with an arbitrary number of integration points along the thickness direction. Several special treatments are applied to the SHB elements to avoid all locking phenomena and guarantee the accuracy and efficiency of the simulations. These solid–shell elements have been implemented into ABAQUS using both static/implicit and dynamic/explicit versions. Several popular static and dynamic benchmark tests as well as sheet metal forming simulations are conducted to assess the performance of these SHB elements.
